Claims.

The present invention relates to a valve for vessels which are used inaerating liquids.

It more particularly relates to a valve used with a rechargeable syphonbottle'which is used 5 to aerate water with carbon dioxide. The carbondioxide under high pressure is introduced into the bottle from a smallcapsule which is associated with the valve when it is desired to aeratethe water. The valve will control the admission of the gas to the bottleand at the same time it serves to regulate the discharge of the aeratedor charged liquid in the vessel when it is to be used.

Various constructions of valves of this type have been employed in thepast but there has always been one great disadvantage attending theiruse. Whenever they have been used on a syphon bottle there has alwaysbeen the danger that the bottle or the valve would burst or ex- ,20plode due to the existence of a high pressure in the vessel. The dangerof the vessel bursting has been present particularly when the vessel hasbeen made of a material which could not withstand high pressure, as forinstance a glass 5 bottle. This danger of excessive pressure may arisefrom various causes such as an undisclosed defect in the vessel itself,an overcharge of gas in the capsule, or the presence of too much liquidin the vessel. Obviously this is a danger which 30 must be avoided inorder to make the use of the.

syphon bottles safe for the ordinary consumer.

Accordingly, it is an object of this invention to prevent any burstingof the vessel.

It is a further object to provide a means in 3:, the valve which willburst and relieve the excess pressure in the bottle when the pressurerises provision of a disc on the valve which will burst 45 before thevessel can burst, if the pressurein the vessel becomes excessive.

' These and other objects will be apparent upon reference to thefollowing specification of which the drawing is a part and in which likenumerals -50 of reference refer to the same parts in each of the' views.

Figure 1 is an elevational view of an embodiment of the invention.Figure 2 is aview in cross section of the valve 55 taken on 8 Planethrough the center of the valve and at right angles to the view shown inFigure 1. With reference to Figure 1, the valve l is mounted on thevessel 3 in any appropriate manner. The valve is provided with a spout 5through which the contents of the bottle are dis- 5 charged after theliquid has been aerated.

Opposite to the spout is the connection 7 to which is attached theholder 9 in which the capsule containing the fluid under pressure isplaced when it is desired to aerate the liquid in 10 the vessel 3. Thedetails of the capsule holderv and gas releasing means are not describedsince they form no separable part of the present invention and are wellknown in the art.

Referring to Figure 2, the valve consists of the 15 body H which isprovided with threads l3 by means of which the valve is attached to thevessel 3. In thebody H is a recess l5 which is designed to overlie thetop of the bottle or vessel 3. The bottle usually carries a washer whichfits into the recess I! and this insures a tight joint between the valveand the vessel. The body is also provided with a chamber I!) which isterminated at its upper end by a seat 2| surrounding a passage 23leading from the chamber I9. 25 There is a restricted portion 25 in thepassage 23 which serves as a guide for the valve stem 21 which may belongitudinally moved in the passage.

Secured to one end of the stem 21, by the threads 29, is the valveproper 3| which carries a valve facing 33 made of rubber or some otherresilient material. By using a material of this nature the contactbetween the valve proper and the seat is made leakage proof so that noneof 35 the excess aerating medium, over that required to aerate theliquid and which is the pressure medium employed to discharge the liquidfrom the vessel, can escape.

At the opposite end of the stem 21 is a push 40 button 33 which isguided by the walls of the chamber 35 in the body II. Formed on the wallof the chamber 35 are projections 31 which limit the downward movementof the button 33.

.A recess 39 is formed in the upper surface of a portion 40 of the valvebody ll projecting within the chamber 35. A resilient rubber gasket 4|closely encompassing the valve stem 21 is received within the recess andserves to make a gas tight joint with the stem. A coiled spring 45 bearsat one end against the inner surface of the push button and at the otherend on a cupped washer 43 resting on the gasket 45, and encircling thevalve stem 21. This spring serves to yieldingly maintain the valveproper 3| in its normally seated position and also to insure a leak.-,

the spout opening W and out through the spout 5. V

In order to prevent the bursting, of the vessel upon development of anexcess pressure for any reason whatever a safety device is providedcomprising a frangible disc 55 and a sealing gasket 53 secured inposition over the outer end of a the cap of the bushing 51 is provided aslot SI.

The slot serves two valuable functions. It serves as a means to removethe bushing when it is desired to replace the frangible disc, by usinga' screw driver, coin or other similar object as a tool. It also is themeans by which the gas may be relieved into the atmosphere when thefrangible disc bursts due to an excessive pressure.

The frangible disc 55 is made of some material which will rupture'at apredetermined pressure. Hence, if the pressure in the bottle should riseto that pressure, the disc will rupture and allow the pressure to fall.It can thus be seen that if the rupturing pressure is carefully chosenthe pressure in the bottle can never rise to a point where it would besuflicient to burst the vessel or valve head. Hence all dangers ofexplosion of any part of the syphon bottle and valve are entirelyremoved.

With the present construction the disc may be replaced very easily andthe vessel may again be used with safety once the dangerous conditionhas been eliminated.

From theforegoing disclosure it will be apparent that this inventionresides in certain principles of construction which may be employed inother physical forms of apparatus without departure. therefrom. It isapparent, therefore, that the form of apparatus illustrated in thedrawing for the purpose of disclosure has been given solely in anillustrative sense and not in any limiting sense. The scope of thisinvention is best defined by the appended claims.
